Where are you likely to get a speeding ticket this holiday weekend?

But how do you know which states and cities are most likely to ruin your Memorial Day vacation by issuing you that ticket? States don't track traffic ticket data for all of their jurisdictions. And most municipalities don't want to publicize their ticket-happy ways for fear of being labeled speed traps.

Luckily, the National Motorists Association (NMA) – a motorists' rights group that has been helping drivers fight traffic tickets for 30 years – has updated its traffic ticket rankings to give holiday travelers some insight into which locales are most likely to ticket them.

This year the NMA expanded its rankings to include the top 10 metro areas for traffic tickets. Drivers will want to be especially vigilant in Atlanta, Los Angeles, Dallas-Fort Worth, Miami and New York City.

Obviously, these rankings aren't perfect (search queries can be impacted by a number of different factors), but the NMA has found that the lists correspond well to its day-to-day experiences helping motorists fight traffic tickets.
